"Oh my goodness, if you last a minute there you have my absolute and total respect."

After signing a waiver, undergoing a medical and psychological exam, and paying for the event with a bag of dog food, Brandon Vance walked into Mckamey Manor.

The waiver Vance signed gave those who work at McKamey Manor permission to use his fears against him.

We were able to speak with Vance less than 24 hours after he tapped out. Vance lasted 2 hours and 30 minutes. He said those minutes felt like hours and that the experience took a toll on his body.

"Something really weird medically happened to me. I couldn't stand up anymore, and that was just due to... I really don't know why... I think my equilibrium was off for some reason," said Vance.

The army reservist also signed a non-disclosure form, which makes it difficult for us to know exactly what happened inside McKamey Manor.

"I'm extremely tired. I'm very very sore. I have a few bruises. My knees are all scraped up and cut up. You know you're bear crawling on rocks and stuff... it is what it is."

Vance said there is nothing you can do to prepare for McKamey Manor, but added it's not a torture house like some think.

"After going through it, I never thought that my life was in danger... you know that nothing could have ever happened to you. They take very good care of you."

That is why Vance said he's ready for round two.

McKamey Manor is a three-phase extreme horror house that no one has ever completed. The final part is conducted somewhere in the Huntsville area on 16 acres of property. The Huntsville Police Department and the Madison County Sheriff's Office tell WHNT they've never heard of it and have no idea where it is.
